Britney (don't want to watch a show full of lip syncing and horrible dancing)
Rihanna (vocals are meh, new songs are meh)
Katy Perry (live vocals suck, but are getting better, I'll give her that)
Ke$ha (she does have good vocals without the autotune, songs are meh tho)
Xtina (don't like her)
I would say Taylor, but I bought tickets for my ex and me to go, so I can't say I wouldn't see her live
